So two months ago, this spot appeared on my head. I went to a dermatologist to see what was wrong and he diagnosed me with alopecia areata. I have PCOS which causes me to have thyroid problems, a possible connection to this. I am only 18 and very scared as I already have many other health issues and my self confidence now is already extremely low. Does this look like it will develop into alopecia totalis because I am so young? How long will it take for more spots/thinning to happen? I’ve been prescribed a topical steroid but haven’t started using it yet. What do I do?
